Three stages of Alzheimer's disease

Alzheimer's disease is a progressive disease. This means that patients will increasingly show the symptoms of the disease. As this progression tends to be accompanied by distinct symptoms, the disease is typically divided into three stages:
The first stage of the disease is called the mild stage or early-stage Alzheimer. This stage is characterised by impaired mental ability as well as mood swings.
The second stage is called the moderate stage or mid-stage Alzheimer. During this stage behavioural disturbances usually increasingly develop.
In the advanced stage or late-stage Alzheimer physical problems are dominant.
